Experimental Investigations of Carbon Fiber Reinforced Polymer Composites and Their Constituents to Determine Their Elastic Material Properties and Complementary Inhomogeneous Experiments with Local Strain Considerations

Abstract Composite materials, such as fiber reinforced polymers, become increasingly important due to their excellent mechanical and lightweight properties. In this respect, paper reports the characterization of a unidirectional carbon polymer composite material. Particularly, behavior overall individual constituents is investigated. To end, tensile shear tests are performed for composite. As result, statistics five transversely isotropic material parameters can be established For description properties constituents, well matrix carried out. addition, volume fraction fibers in determined experimentally using an ashing technique Archimedes’ principle. Young’s modulus fiber, transverse contraction matrix, concluded. The resulting on both scales useful application validation different models homogenization methods. Finally, order validate obtained future, inhomogeneous were performed, once flat plate with hole semicircular notches.
